Hi All,  
We have 4 Appliance (Prod and DR), so when I fire SEMP query (it will come blind count and current message in the queue) will get all queue start, And that SEMP query is automated. And last week my Appliance failover from primary to secondary and I didn’t get any data from that SEMP query, so is their any SEMP query avalable to identify which Appliance is active.  
If yes please provide the SEMP query, so based on that I will modify my existing SEMP query.

Hi @Muddam_Pullaiah, you’ll need to use the (Legacy SEMP API)[[SEMP](https://docs.solace.com/SEMP/Using-Legacy-SEMP.htm)] as SEMP v2 doesn’t support this yet. The query you need is to get the redundancy status:

```auto
  <redundancy/>
</show>

```

Look for the `<virtual-routers>` tag, then the `<primary>`, and check inside `<status><activity>`
